Last week I started printing this Type VII C model I found. I used PLA and printed it hollow so that I can fiberglass the interior.

I'm still trying figure out how to post properly here and now I've inadvertently closed the window for attachments and can't figure out how to restore it to finish uploading my pics -

The hull looks O.K. - You are rocking away at this.
If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.Comment

It needs quite a bit of prep work before i can epoxy the outside, the model wasn't that great but it would be a good learning experience. I already started making some brass linkage for the dive planes.
I'm actually very interested in Printing some of the models Bob sells in resin but I wanted to tinker on this one first. I may try printing this one in ABS like resin as well.Last edited by Wizzard033; 09-20-2023, 06:24 PM.Comment

Wouldn't the exothermic reaction of the curing resin cause the the PLA to deform?Make it simple, make strong, make it work!Comment

I plan to find out. I figured on only applying a 2oz cloth on the interior. I'm going to use Bob Smith 30 minute epoxy.
if it doen't work this way my 13 year old son has his eye on it even as a static display in his room. He wants to paint and detail a Type VII badly. lol
I might even try printing it on my resin printer in the same manorLast edited by Wizzard033; 09-20-2023, 10:32 PM.Comment

Is that epoxy long term - stable in water, i.e. is it just like 5-min epoxy?Comment

I have not tested it, I believe it is stable in water. I think the short time it spends in water will not impact it and with a coat of paint even less so.If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.Comment

I've worked with a lot of adhesives in the aerospace world, and this is one of my all-time favorites for slow-cure, 2-part epoxys. This is lab-grade, clear epoxy, which has a 1/2 hour working time, and cures within 12 hours - faster if you use an oven.
Hardman makes a five-minute (red label) epoxy, but it can't come close to the (green) label product for low heat generation, high adhesion, and hardness. Excellent stuff.
